Classification Flashcards
Give an example of a monera?
Any bacteria is found in this group, single called organism with no nucleus
Give Alan example of a fungi.
Mushroom, moulds and yeasts- they are decomposers , breakdown living and dead material
Give an example of a protist?
Algae is an example, can move around and live in water
Name some differences between plants and animals?
Plants have chlorophyll for converting sunlight into food.
Plants cells have a cell wall to give them structure
Describe 7 characteristics of living things.
- Can reproduce
- Consume energy
- Produce waste
- respond to their environment
- Made up of cells
Animals can be further divided into?
Based on skeleton
Vertebrates ( us) and invertebrates (crabs)
Plants can be further divided into two groups.
Flowering and non flowering plants.
Vertebrates an further divided into 5 groups what are they
Mammals Amphibians Birds Fish Reptiles
Name the 5 kingdoms in the living world
Animals
Plants
Protests ( usually live in water - single called and have a nucleus)
Fungi
Monera (bacteria) cells that don’t have a nucleus
Name an Australian plant that shows adoption to its environment
The Banksia
It’s seeds only open after a fire has passed
Name an Australian animal that shows an adaption to its environment
Kangaroo
It’s always pregnant and only develops when conditions are good ( avoids droughts and low water)
Legs like springs conserve energy
What does a food chain show
The flow of energy through feeding relationships- arrows how’s direction of energy flow
What Is a decomposer
Decomposers recycles material from each feeding level of a food chain and return nutrients to thespians the atmosphere.
What are scavengers
Opportunistic feeders that take food from each level of a feed web
What is a producers?
Starts food web, producers carry out photosynthesis
Allow energy to enter the ecosystem
What is photosynthesis
Is a chemical process that converts sunlight and carbon dioxide into energy ( sugar)
Carbon dioxide + water +sunlight = sugar + oxygen
Where does photosynthesis occur in the plant
In the chloroplasts which contain the chemical chlorophyll which traps the sunlight
Name some types of decomposers
Worms, fungi and some bacteria
Why do biologists use classification keys
It allows biologists To organise and identify organisms
Name a beneficial bacteria and fungi
Nitrogen fixing bacteria, they convert unreactive nitrogen into forms that plants can use
Bacteria in cheese production
Fungi is used in penicillin production
How can human activities affect food webs
In some cases they can alter them drastically by
- hunting apex predators to extinction ( wolves)
- pollution ( heavy metals)
- over fishing
